A 'furthe'rohjeet is to provide an appara' tus of this character in Which the dumping operation requires no hand labor other than initiating the starting of the operation and which is comparatively simple in construc- 'tion, not liable to get out jot repair, and which will most. efficiently perform the tunetions for Whi'C'h it is intended.

Vith these and "other objects in view, the invention consists in certain novel features of construction -and combinations and arrangements of parts, i which will be'i'nore fully l'rere'inafte-r described and pointed out in the claims,

In the accompanying dra wings,

Figure 9 is a fragmentary view in section A represents m stem-em "frame 13 "a !-"t i Y. movable carriage onthe frame A, and a car adapted to be run onto and 0d the car- 'ge, 'allofyvlrich Wlll be more any hereinafter described. 1

The trameA of structural "steel isof gen-.-

eral rectangular form and is adapted to rest upon the ground, or upon 'a shpp'ort, in such :position as desired. I have indicated the frame as supported so as to al'l-ow'the ear to be dumped over the edge "of a .shi'll; p'ttrtidular reference being niade to Figures 2 and 4, but it is to be understood that the 'frame may be located at any point Where the dumping operation is desired.

' The carriage B is of general oblong shape, positioned transversely "of the support A and having a pair of vvheelsl and2'ateach end. The Wheels 1 are .adapted to runi'ipon rails 3; and the Wheels 9 are adapted to run uip'on rails 4. v

These Tails 3 and 4 curve upwardly from the plane or; the normal 'or initial position of the carria e, and terminate at their extremities in t'ie for'm of hooks '5 'and 6; respectively, the hook '6 being in a'pl'ane appreciably above the hook '5 and spaced from the hook 5 the distance bet'v-v'e'en the Wheels 1 and 2. p 7 p p Furthermore, it will be noted by referenc'e to Figures 2 and'c, that the liook 6 projects in a plane beyond the "hook 5 so when the carriage is moved to the extremity of the tracks or rails the latter Wil'l'be moved to "any angle pastthe vertical plane or past the perpendicular so i that the entire cont'ents of-"the car C supported on the carriage win be dumped.

The cariiageB made vvith a pair of rails .7, constituting track n hi'ch registers With'the service track 8; indicated bydjotted lines in Figure '1, "sothat 'therar C be run from the service track rlirctiy en to the tracks er the carriage until the wheels Set the car engage "stop bloeks 1'0 onthe Garriage to limit thejfurther'inovement 10f thegcar and centerth'e car on the jcairiage.

To pr t afl d l, r trograde, imote- {mer t of the ca-1* I provide, bloeks-gl l fixedi a sha t 2 moun ed .ll; e ar g nd these blocks 11 move upwardly when 'peia mitted and hold the car against movement. The shaft 12 is formed with short crank .arms13 connected by springs .14 with fixed bars 15 on the carriage so that these springs normally tend to hold the free ends of the blocks 11 inelevated position against wheels 9 of the car C. On the shaft 12 a hand lever the carriage, but when the forward pair of wheels engages the blocks 10 the blocks 11 will spring upwardly against the other pair of wheels and confine the wheels between said blocks 1-0 and 11 so thatthere can be no accidental movement of the wheels on the rails 7. 7

To prevent any possibility of the cars displacement from the carriage during the dumping operation, I secure angle brackets 17 to the under face of the car body 18 and these angle brackets ride under angle bars 19 on supports 20 which are fixedto the carriage, as clearly indicated in Figures 2 and 4. In other words, these angle bars 19 constitute rails and the anglebrackets 17 move under the rails so that they prevent [any possibility of the wheels 9 of the car G from leaving the rails 7. i

The supporting frame A at its dumping end and at both sides thereon is provided with two pairs of shafts 21 and 22. These shafts carry sprocket wheels 23 and 24, respectively. At the other end of the supporting frame A similar pairs of sprocket wheels 25 and 26 are located. Sprocket wheels 25 are mounted on shafts 27 and sprocket wheels 26 are secured to a shaft 28 which is common to both of the sprocket wheels and extends throughout substantially the transverse dimension of the supporting frame A at one end, as clearly indicated in Figures 1 and 6.

29 represents an axle which is mounted on. wheels 30. The latter are movable in channel rails31 secured to the frame A. The axle 29 supports a pair of sleeves 32 having lugs 33 and 34 at opposite sides thereof. Each lug 33 is adjustably connected to one endof the chain 35, and the other lugs 34 are connected to the opposite ends of thesame chain 35. As clearly indicated, there are two of these chains 35 and the chains extend from the lugs 34 longitudinally of the support A, thence under the sprocket wheels 24, thence around the sprocket wheels '23, thence longitudinally of theframe A; around sprocket wheels 26,

under sprocket wheels 25, andare secured of the shaft 28 the axle 29 is caused to move longitudinally of the supportin frame, the wheels 30 moving along the c annel rails 31 and held against vertical movement by reason of said channel rails.

A shaft 36 is mounted onthe bottom of the carriage B, and collars 37 on said shaft 36 are connected by links 38 with collars 39 on axle 29, so that when the axle is caused to move the carriage is also moved, as will be readily understood.

1 preferably provide rollers 40 on the shaft36 where said shaftwill engage the runs of the chains 35 to prevent undue wear and reduce friction to a minimum.

I would call particular attention, to the mechanism for transmitting motion to the shaft 28, and refer particularly to Figures 6, 7, 8 and 9 ofthe drawing. 41 indicates a motor, which is preferably an electric motor, on the shaft 42 of which I secure a sprocket wheel 43 which is connected by a chain 44 with a sprocket wheel 45 on a shaft 46, said shafts being suitably mounted on the supporting frame A The shaft 46 carries a bevel pinion '47 which always in mesh with a pair of bevel gears 48 and 49, respectively, and these gear wheels 48 and 49 are loose on a shaft 50 which is secured on frame A parallel to the shaft 28. i y

51 and 52 represent clutches keyed to slide on the shaft 50. To these clutches arms 53 are operatively connected, and said arms 53 'form fixed parts of blocks 54 mounted to slide upon a shaft 55. The shaft 55 has a pinion 56 secured thereon, which meshes witha gear wheel 57 on shaft 28, and saidgear wheel 57 is driven by a pinion 59 secured to shaft 50.

To initiate the starting movement of the apparatus I employ preferably a hand lever 60 pivotally connected to support A and having a rod 61 connected thereto. This rod 61 projects throughthe blocks 54 and has adjustable stops 62-and 63. A second rod 64 extends through the blocks 54 and carries adjustable stops 65 and 66 thereon. These stops.62 and 63 and 65 and 66 are preferably collars which are loose on the rods and fixed thereto in any approved manner. the purpose.

The shaft 55 throughout the intermediate portion of its length is screwthreaded and a nut 67 is mounted on this threaded portion I have indicated pins or screws for of the shaft 55, and the rod 64 is-projected The operation of this driving mechanism,

indicated in Figures 1 and 6 ofthe drawing, is asfollows: The parts are shown in a neutral position. To start the operation the lever 60 is moved to cause the rod 61 to move longitudinally and the stop 62 will force the block 54 and the clutch 51 in a direction to lock the clutch 51 and gear wheel 48 together. Then motion will be transmitted from the pinion 47 to the gear wheel 48 to turn the shaft 50. Motion will be transmitted from shaft 50 through the medium of the gear wheels 59, 57 and 56 to turn the shafts 28 and 55. The turning of the shaft 50 causes a movement of the chains 35 to move the carriage and the car to a dumping position, as above explained,and during this movement the turning of the shaft 55 will cause the nut 67 to move longitudinally of the shaft until it engages the stop 65. This stop will be. against the face of block 54 when clutch 51 is in engagement with the gear wheel 48, so that as the nut 67 engages the stop 65 it will force the block 54 in a direction to move the clutch 51 away from its engagement with the gear wheel 48 and stop the movement of the carriage as the latter reaches its full dumping position. l/Vhen the load is completely dumped, the operator moves the lever 15 in the direction opposite to the first defined movement to draw the stop 63 against the block 54 and move the clutch 52 into engagement with the gear wheel 49. The shaft 28 will then be turned in the direction opposite to that above described until it comes into contact with the stop 66 against block 54 and will force the clutch 52 away from gear Wheel 49 and stop the transmission of motion to the carriage.

It will thus be noted that a single operafor controlling the movement of lever 60 can initiate the movement of the carriage in both directions and that when said motion or movement is initiated, the movement will be completed and automatically stopped without any further attention of the operator. Thus a car can beloaded on to the carriage and quickly and effeciently dumped, requiring no labor in the operation other than the movement of the car on the carriage and the initiation of movement by the operation of the lever 60.

lVhile I have illustrated what I believe to be a preferred embodiment of my invention it is obvious that various changes and alterations might be made in the general form of the parts described without departing from the spirit of the invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.
